EDWARD S. CIR-ADDOCK, OF NEW YORK, N. Y., ASSIGNOR TO TABRIZ RENOVATINGCOMPANY, OF JERSEY CITY, NEW JERSEY, A CORPORATION OF NEW JERSEY.

RUG-TREATING MACHINE.

To all whom it may concern:

Be it known that I, EDWARD S. CnADDooK, acitizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Rug-TreatingMachines, of which the following is a specification.

My invention relates particularly to mechanism for the treatment ofheavy pile fabric rugs or carpets by washing, stripping, fixing orcoloring.

Oriental rugs and the like are very difiicult to handle and in the pasttheir treatment has been unsatisfactory on account of the matting of thepile threads, the running of the colors and the slow speed and expenseof the old operations.

My objects are to simplify the handling of the rugs and to expedite theoperations without injury to the rugs and to obtain more uniformresults.

The invention consists in a tank for containing the treating liquid, anda special form of reciprocating open-work frame for containing the rugswhich are thus caused to move back and forth in the liquid so that thedifferent layers of the same rug or a number of rugs are moved back andforth against each other and the liquid is well rubbed into the pilethreads and the body of the fabric or fabrics.

Figure 1, is a side view and longitudinal section of a machine embodyingthe improvements of my invention. Fig. 2, is a plan view of the treatingtank and frame. Fig. 3, is a transverse sectional view of the tank andframe.

Tank 1 is of special construction to hold the desired liquid forstripping, washing or coloring as the case may be. The liquid may beintroduced through a pipe 2 and hot water or steam may be introducedthrough the same pipe or a separate pipe 3. The liquid may be drainedthrough the outlet 4. A long handled plug 5 is preferably provided forthis outlet.

The frame 6 specially constructed for the purpose of this invention asmore fully described hereinafter has a hook-like upright 7 at eachcorner by means of which the frame is suspended from shafts 8 and 9.These shafts are carried by carriages 10, 10 and 11, 11 which areadapted to be moved back and Specification of Letters Patent.

forth on the tracks 12, 12 along the upper side edges of the tank 1.

The frame 6 reciprocates slowly in the tank by automatic means such asshown in Fig. 1. The driving pulley 13 and pinion 14 are fixed on shaft15. Pinion 14 meshes with gear wheel 16 on shaft 17. The crank 18 alsofixed on shaft 17 is connected by rod 19 to lever 20 which is hinged at21 at the lower end. The upper end of lever 20 is connected by link 22to shaft 8. Therotation of the pulley 13 is thus transformed in to areciprocating motion of the shaft 8 carriages 10, 10, frame 6, shaft 9and carriages made of angle irons braced and reinforced.

substantially as shown to give sufficient strength to carry the loads tobe imposed upon it. The bottom, sides and ends are each constructedpreferably of slats or bars of wood such as 23, 24 and 25 all roundedtoward the interior of the frame so as to pre vent injury to the rugs.The slats 23 of the bottom are all fastened to cross pieces such as 26so that they may all be inserted or re moved from the metal skeleton ofthe frame at once. The sides and ends are similarly constructed, and allof their slats are vertical so that while the liquid is free to passback and forth, the rugs cannot slip through and will not tend to clogup the passages. Along the upper edges of the sides of the frame areguards 27, 27 extending over the upper ends of the bars or slats 24, 24and up close to the sides of the tank 1 so as to prevent injury to therugs when putting them into or taking them from the tank.

The rugs are laid flat in the bottom of the frame and on top of eachother, such rugs as are larger than the bottom of the frame being foldedback and forth. As the frame with the rugs is reciprocated back andforth in the tank, the liquid surges back and forth through the ends ofthe frame and beneath, between and over the rugs, reaching the bodies ofthe rugs at the base of the pile threads. The rugs themselves beingheavy and laid flat, shift back and forth at the end of each stroke sothat a rubbing motion takes place between every two adjacent layerswhich accelerates the action. I prefer to have the bottom reticulated asshown, like the sides, so as to permit a more free circulation of liquidbut the openings should not be large enough to permit the rugs to fallor work through. The rugs should be kept clear from the sides and bottomof the tank to prevent injury and to keep them clean for there is atendency for dirt and colors to collect particularly at the bottom ofthe tank.

What I claim is l. A rug treating machine, comprising in combination, aliquid containing tank having longitudinal tracks along its side edges,supporting wheels running on said tracks, a rug holding frame supportedby said wheels, said frame being of openwork construction with a bottomformed of spaced slats extending transversely of the frame whereby to retard longitudinal shifting movement of the rugs during longitudinalreciprocation of the frame and to thereby exert a scrubbing action onsuch rugs, the sides and ends of the frame consisting of spaced slatsdisposed upright to thereby prevent the rugs laid flatwise in the framefrom slipping out of the frame into the tank and means for reciprocatingthe frame containing the rugs longitudinally through the tank to therebyscrub the rugs against each other and against the slats of the frame andto force the liquid freely through and around the rugs.

2. A rug treating machine, comprising in combination, a liquidcontaining tank having longitudinal tracks along its side edges,

supporting wheels running on said tracks, a rug holding frame supportedby said wheels, said frame being of openwork construction with a bottomformed of spaced slats extending transversely of the frame whereby toretard longitudinal shifting movement of the rugs during longitudinalreciprocation of the frame and to thereby exert a scrubbing action onsuch rugs, the sides and the ends of the frame consisting of spacedslats disposed upright to thereby prevent the rugs laid fiatwise in theframe from slipping out of the frame into the tank, strips secured tothe upper edges of the frame, overlying the upper ends of the uprightslats to thereby prevent rugs thrown into the frame from catching on theupper ends of the slats, said strips also extending outward relativelyclose to the walls of the tank to prevent the rugs which are beingthrown into the frame from slipping in between the frame and the wall ofthe tank, and means for reciprocating the frame containing the rugslongitudinally through the tank to thereby scrub the rugs against eachother and against the slats of the frame and to force the liquid freelythrough and around the rugs.
